Description

Technical Field

[0001] This utility model relates to the field of packaging and transportation technology for AGV (Automated Guided Vehicle) vehicles, specifically a transportation packaging box for heavy-duty AGV vehicles. Background Technology

[0002] Automated Guided Vehicles (AGVs), as core transportation equipment in modern intelligent logistics systems, achieve unmanned cargo handling operations through pre-set path navigation systems and are widely used in manufacturing, warehousing, and logistics. Existing AGV equipment generally uses metal materials for the chassis and top support structure, while side protection mostly relies on a combination of injection-molded plastic covers and flexible anti-collision strips. Since AGVs frequently come into contact with external objects such as shelves and transfer equipment during operation, their lateral collision protection performance directly determines the equipment's service life and operational safety.

[0003] Current AGV (Automated Guided Vehicle) transport packaging designs suffer from the following technical defects: insufficient bottom positioning, as traditional pallet packaging lacks a precise matching and positioning mechanism with the AGV chassis structure, making it prone to relative displacement during transportation and causing scratches on the equipment surface; weak side protection, with existing plastic covers having limited impact resistance, and anti-collision strips only able to buffer low-speed collisions, failing to effectively cope with high-frequency, multi-angle accidental impacts during transportation; and a lack of functional integration, with the bottom positioning structure and side protection components designed separately, failing to form a collaborative protection system, increasing packaging complexity while reducing overall reliability.

[0004] The aforementioned technical bottlenecks severely restrict the transportation safety of AGV equipment under complex working conditions, and there is an urgent need to develop an integrated packaging solution that combines precise positioning and multi-dimensional protection. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a transport packaging box for heavy-duty AGV carts, which can increase the accurate positioning and limiting fixation of the packaging box for the AGV cart chassis, and provide buffer protection for the AGV carts at multiple angles during transportation.

[0006] To achieve the above objectives, a transport packaging box for a heavy-duty AGV (Automated Guided Vehicle) is designed, comprising a pallet, side panels disposed around the perimeter of the pallet, a top cover disposed on the top of the side panels, and the AGV mounted on the pallet. The box also includes a central crossbar, which is positioned along the central symmetrical line of the pallet in a front-to-back direction. A set of padding structures is disposed on both sides of the central crossbar. Each padding structure includes two first pads disposed at the front and rear of the pallet, respectively. The first pads are parallel to the central crossbar, with a gap between the front and rear first pads. The front side of the front first pad is aligned with the front edge of the pallet, and the rear side of the rear first pad is aligned with the pallet. The rear edges are aligned; at least one third crossbar is set at the corner of the pallet and extends in the left and right direction, one end of the third crossbar abuts against the first pad; at least one fourth crossbar is set parallel to the third crossbar and is set in the gap between the opposing first pads; the third crossbar, the fourth crossbar and the first pad together form a three-sided enclosure and limiting frame structure; it also includes several pressure plates set on the top of the AGV trolley, the two ends of the pressure plates are provided with packing strap slots, the periphery of the pallet is provided with packing strap slots, the packing straps surround the AGV trolley and the pallet and are locked in the packing strap slots of the pressure plates and the pallet to form a limiting.

[0007] Preferably, the present invention further includes: two first limiting seats symmetrically arranged along the front and rear sides of the tray; two second limiting seats symmetrically arranged along the left and right sides of the tray; and at least two third limiting seats diagonally symmetrically distributed with the geometric center of the tray as a reference point; the first limiting seats are disposed on the first pad and include: a first crossbar disposed on the first pad and first baffles respectively disposed at both ends of the first crossbar, the outer side of the first baffles being aligned with the edge of the tray, and the inner side of the first baffles extending out to form the first crossbar and forming an L-shaped structure with the opening facing downward; the second limiting seats are disposed on the second pad and include: a second crossbar disposed on the second pad and second baffles respectively disposed at both ends of the second crossbar, the outer side of the second baffles being aligned with the edge of the tray, and the inner side of the second baffles extending out to form the second crossbar and forming an L-shaped structure with the opening facing downward; the third limiting seats are composed of a third crossbar and a fourth crossbar.

[0008] Preferably, the present invention further includes: the two ends of the central crossbar are respectively engaged in the gap between the first crossbar and the tray in the two first limiting seats.

[0009] Preferably, the present invention further includes: the three-sided enclosure blocking and limiting frame structure is an open frame, and two wheel stop rods parallel to the third and fourth crossbars are provided at the open. The wheel stop rods are arranged between the third and fourth crossbars, and the end of the wheel stop rods near the frame structure is provided with an inclined surface.

[0010] Preferably, the present invention further includes: the inner structure of the packaging box is provided with felt on the contact surface between the packaging box and the AGV trolley.

[0011] Compared with the prior art, the advantages of this utility model are:

[0012] By setting up a multi-dimensional limiting structure that matches the profile of the AGV chassis and establishes it in the circumferential direction of the traveling wheels, the normal direction of the chassis bottom surface, and the direction of the top plate support surface, the positioning of the equipment in three-dimensional space is achieved. A multi-component collaborative clamping mechanism is adopted to implement multi-angle elastic clamping on the traveling wheels, chassis reinforcing ribs, and top plate, forming a distributed constraint system that runs through the mechanical transmission path of the equipment. The lateral impact-resistant components and longitudinal buffer modules are integrated to simultaneously resolve the forward and backward inertial impact forces and lateral off-center stresses through an anisotropic damping structure. The limiting structure and protective components adopt a topology-optimized integrated molding design, which reduces the structural weight compared with the traditional split packaging while ensuring the rigidity and strength index.

[0018] To make the purpose, principle and structure of this utility model clearer, the following description is provided in conjunction with the accompanying drawings and specific embodiments.

[0019] Combination Figure 1-4 The present invention provides a transport packaging box for a heavy-duty AGV trolley, which will be described in detail below. Figure 3 Positions closer to the forward-looking direction are considered forward, and positions farther from the forward-looking direction are considered backward. Figure 3 Based on the left side, the direction to the left is left-hand, and the direction to the right is right-hand.

[0020] The structural composition and limiting principle of the heavy-duty AGV transport packaging box described in this embodiment are as follows:

[0021] The packaging box uses a rectangular pallet 1 as its base, with side plates 1.1 vertically fixed to its perimeter and a removable top cover 1.2 covering its top.

[0022] Several strapping grooves 2 are evenly distributed around the perimeter of the pallet 1 for attaching and securing the strapping.

[0023] Two sets of first limiting seats 3 are symmetrically arranged along the front and rear sides of the pallet 1; two sets of second limiting seats 4 are symmetrically arranged along the left and right sides of the pallet 1; at least two third limiting seats 5 are set at diagonal positions with the geometric center of the pallet 1 as the reference point; and a central crossbar 8 extending in the front and rear directions is set on the left and right central axis of symmetry of the pallet 1.

[0024] The first limiting seat 3 includes: two first pads 3.1 extending in the front-rear direction, a first crossbar 3.2 straddling the first pads 3.1, and a first baffle 3.3 fixedly connected to both ends of the top surface of the first crossbar 3.2; the outer side of the first baffle 3.3 is flush with the edge of the tray 1, and the inner side extends toward the center of the tray 1, forming an L-shaped limiting cavity with the first crossbar 3.2 with an opening facing downward, for engaging the lower edge of the AGV trolley traveling section edge 10. The first pads 3.1 are symmetrically arranged on both sides of the central crossbar 8, and a gap is left between the first pads 3.1 of the two opposing first limiting seats 3.

[0025] The second limiting seat 4 includes: two second pads 4.1 extending in the left and right direction, a second crossbar 4.2 straddling the second pads 4.1, and a second baffle 4.3 fixedly connected to both ends of the top surface of the second crossbar 4.2.

[0026] The first limiting seat 3 and the second limiting seat 4 have similar structures, and their limiting cavities are orthogonal, forming a four-way limiting constraint.

[0027] The third limiting seat 5 is located at the corner of the tray 1 and includes a third crossbar 5.1 extending in the left-right direction and a fourth crossbar 5.2 arranged parallel to the third crossbar 5.1. The fourth crossbar 5.2 is located in the gap between two opposing first pads 3.1. Both the third crossbar 5.1 and the fourth crossbar 5.2 are located on the outside of the width direction of the first pads 3.1, forming a three-sided enclosed open frame together with the first pads 3.1 to accommodate the AGV trolley's traveling wheels and limit their movement. The distance between the third crossbar 5.1 and the fourth crossbar 5.2 matches the width of the traveling wheels, forming a clamping action in the width direction.

[0028] The two ends of the central crossbar 8 are embedded in the gap between the first crossbar 3.2 and the tray 1 in the first limiting seat 3, forming a reinforcing rib and improving the overall vibration resistance.

[0029] The wheel stop rod 6 is located at the open end of the open frame formed by the first pad 3.1 and the third limit seat 5, and includes two rods arranged parallel to the third crossbar 5.1. The wheel stop rod 6 is located between two adjacent third crossbars 5.1. The wheel stop rod 6 has a guide slope near the end of the frame to block the displacement of the traveling wheels and to guide the AGV to drive away when it is unpacked from the packaging box.

[0030] The pressure plate 7 consists of several parallel wooden strips installed on the top of the AGV trolley inside the packaging box, arranged along the outline of the AGV trolley's carrying platform 9. Both ends of the pressure plate have strapping slots 2 with the same structure and position as those on the pallet 1. The pressure plate 7 and the pallet 1 work together to form upper and lower clamping surfaces, and the strapping passes through the strapping slots 2 for bidirectional fixation.

[0031] A felt layer is bonded to the contact surfaces of pallet 1, the limiting components, and the AGV trolley to prevent surface wear caused by rigid contact during transportation.

[0032] The AGV's traveling section edge 10 is embedded in the L-shaped limiting cavity of the first limiting seat 3 and the second limiting seat 4. Vertical displacement is suppressed by the upper and lower clamping of the first baffle 3.3, the second baffle 4.3, the first crossbar 3.2, and the second crossbar 4.2. (See [reference]). Figure 4 The relationship between the middle running section edge 10 and the limiting cavity.

[0033] The running wheels at the bottom of the AGV are embedded in the frame of the third limiting seat 5, and are constrained on both sides by the spacing of the third crossbar 5.1. The front edge of the wheel abuts against the wheel stop bar 6 to achieve bidirectional displacement constraint.

[0034] The central crossbar 8 and the first limiting seat 3 form a truss structure to distribute the transport vibration load and prevent the L-shaped limiting cavity from deforming and failing due to impact force.

[0035] The specific workflow is as follows:

[0036] The AGV trolley is hoisted into the packaging box, and the AGV trolley's running wheels are locked in the frame of the third limit seat 5. The other components of the first limit seat 3 and the second limit seat 4 are fully installed on the first pad 3.1 and the second pad 4.1 of the pallet 1, so that the L-shaped limiting cavity of the first limit seat 3 and the second limit seat 4 forms a locking limit with the edge 10 of the trolley's running part.

[0037] The cover plate 7 is placed on top of the AGV trolley, and the packing strap is wrapped around the tray 1 and the cover plate 7 in sequence and locked in the packing strap groove 2 to complete the binding.

[0038] After the packing straps are removed during the unloading phase, the AGV trolley is pulled along the inclined surface of wheel stop 6 to disengage it from the limit assembly.

[0039] The L-shaped cavity, frame clamping, and inclined plane blocking form a six-degree-of-freedom constraint, improving impact resistance during transportation. Each limiting component can be independently disassembled and replaced to adapt to the transportation needs of different AGV models. The inclined plane guiding design improves loading and unloading efficiency, and the felt protective layer reduces the risk of surface scratches.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and novel concept of this utility model, should be included within the protection scope of this utility model.
